Looked at the wikipedia article for Supercentarian. (refers to someone who has reached 110 years of age). The individual with the longest confirmed lifespan was Jeanne Calment of France. Died in 1997 at an age of 122 years of age.
She would have had an adult perception of the world for an entire century. When she was twenty-two years old, the world of 1997 would have been wild science fiction. A lot can and did change during that period.
I wonder if reaching a hundred will become common in three or four decades.
